for stripping the heads from stalks of a crop of broom corn.

The primary object of the invention is the provision of a broom corn header comprising 1 a wheeled main frame having superposed upon the same an adjustable supplemental frame, thesaid main frame carrying, a bunch delivery wheel, a vertically disposed conveyer for delivering material to the said bunch delivery wheel and the superposed supplemental frame having at its front a sickle cutter to cut the heads from thestalks of the broom corn, means for shifting the severed material onto a conveyor, which latter delivers the same between upper and lower conveyer belts where it is transported to the vertically disposed conveyor on the main frame downwardly to the bunch delivery wheel.

Another object of the invention is the provision of a broom corn header comprising a Wheeled main frame having mounted thereon a superposed frame the latter supporting cutter mechanism for severing the heads from broom corn, conveyor mechanism for receiving the severed material and transporting the same over the supplemental frame to one side thereof where it is carried downwardly on to a delivery mechanism supported by the main frame which delivery mechanism will deposit the severed material in bunches upon the ground during the travel of the machine and mechanism actuated by the wheels of the vehicle to impart movement to thecutter and conveyer mechanisms,

With these and other objects in view the invention for example is carried into practice and executed by the construction which will be hereinafter more fully described and as illustrated in the accompanying drawings bodiment of the invention.

which disclose the preferred form. of emderstood, however, that changes, variations It is to be un--' and modifications may be made such as come properly within the scope of the claims hereunto appended without departing from the spirit of the invention.

In the drawings: Figure 1 is a top plan view ofthe machine. Fig. 2 is a horizontal sectional view. Fig. 3 is a side view. Fig. 4 is a rear end view. Fig. 5 is a vertical sectional View taken centrally of the machine. Fig. 6 is a fragmentary view partly in section of a portion of the bunch delivery wheel and itstrip mechanism.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

In the drawings the numeral 10 designates generally the main frame of the machine which is mounted upon traction wheels 11 fixed to an axle 12 journaled in bearings 13 depending from the said main frame and projecting from the front or forward end of said main frame is a tongue 14 having the usual or ordinary doubletree 15 for the adjustment of the draft animals whereby the machine can be transported over a field in the execution of its work.

Fixed to the main frame at one end thereof is a vertically disposed frame 16 the same being rigidly held in position by brace members 17 connected to the same and to the main frame. Near the top of the vertical frame and mounted in bearings 1.8 is a horizontally disposed rotatable shaft 19 and mounted in'bearings 20 depending from the main frame is a horizontally disposed rotatable shaft 21 and each of which shafts 19 and 21 respectively have fixed thereto flanged belt pulleys 22 spaced from each other and over which are trained conveyer belts 23 the latter adapted to move downwardly and receive their motion from a sprocket wheel 24 fixed to the shaft 21 at one end thereof and over which is trained a sprocket chain 25 which latter is also trained over a sprocket wheel 26 fixed to a stud shaft 27 rotatably mounted in a bearing 28 and carries a gear 29 in mesh with a gear 30 the latter meshing with a combined gear and sprocket wheel 31 which latter has trained thereover a sprocket chain 32 the same also trained over a sprocket Wheel 33 fixed to the rotatable axle 12 actuated by the traction wheels of the machine. I 4

Centrally of the main frame and fixed thereto in spaced relation are vertically disposed boxings or sleeves 34 into which telemgs or sleeves 34 also are supported and held rigid by brace bars 38 which are connected to the main frame and said boXings.

Mounted upon the supplemental frame 36 at its front near one end thereof is a reciprocating sickle blade 39 which is adapted to sever or cut the heads from the stalks upon the advance of the machine and such stalks are guided to the sickle blade by outwardly diverging curved guide arms 49.

Mounted in the supplemental frame 36 directly in rear of the sickle blade 39 is an end-- less transversely movable conveyer 41 the same being trained over shafts 42 and 43 which latter shaft has fixed thereto a cog gear 44 in mesh with a cog gear 45 carried l)?! the end of a shaft 46 journaled as at 47 on the supplemental frame and a distance above the conveyer 41 and upon the said shaft 46 are flanged belt pulleys 48 over which are trained endless belts 49 forming conveyers which latter are also trained over corresponding belt pulleys 50 mounted upon a shaft 51 jour naled upon the supplemental frame adjacent the conveyer 23 supported upon the main frame. Below the belts 49 and spaced a suitable distance therefrom are conveyer belts 52 the latter trained over flanged belt pulleys 53 which are fixed to shafts 54 and 55 journaled in bearings 56 mounted upon the supplemental frame.

Projecting upwardly vertically from the main frame and actuated by the gear 30 is a squared rotatable driven shaft 57 the upper end of which slidably engages a gear 58 retatable therewith and mounted upon a bracket 59 on the supplemental frame. The gear 59 meshes with a gear 60 fixed to a retatable stud. shaft 61 ournaled in the frame and which latter shaft carries a sprocket wheel 63 over which is trained a sprocket chain 64 which latter actuates a sprocket wheel 65 mounted upon the shaft43 to impart movement to the conveyer 41 as the machine advances over a field. Said sprocket chain 64 is also trained over a sprocket wheel 66 mounted upon the end of tie shaft 55 to im art movement to the lower belts 52 whic latter move with the upper belts 49 which receive their motion through the medium of the cog wheel 45 driven by the shaft 43 so that the severed heads upon the conveyer 41 will be transferred between the belts 49 and 52 and carried across the supplemental frame to the downwardly moving conveyer 23 of the main frame.

Connected to the sickle blade 39 is a link rod 67 the same being eccentrically mounted as at 68 to a rotatable disk 69 fixed'to. a

driven shaft 7 O the latter having at its opposite end a sprocket wheel 71 over which is trained the sprocket chain 64 so that reciproeating motion or movement can be imparted to the sickle blade whereby the same will sever the heads from the standing stalks of the crop in a field.

Projecting outwardly from the supplemental frame 36 are upwardly inclined brackets 72 arranged in spaced. relation on opposite sides of the sickle blade 39 and terminating in slotted ends 73 in which is mounted an adjustable shaft 74 supporting a rotatable reel 75 above said sickle blade and is adaited to act upon the severed ma terial cut y the sickle blade to cause the said material to fall upon the conveyor 41 and the said reel 75 is driven by a sprocket wheel 76 over which is driven a sprocket chain 7 7 the latter trained over a combined sprocket wheel and gear 78 which latter is in mesh with. .a gear 79 fixed to the shaft 46 mounted in the supplemental frame. in mesh with the said gear 79 is a gear 89 fixed to a shaft 81 journaled in bearings 82 secured to the front end of the supplemental frame and which shaft 81 carries a stripper roller 83 having stripper blades 84 moun ted peripherally of the roller and arranged in spaced rows which blades 84 are adapted to strip blades or boots from the severed stalks as they are conveyed by the endless belts 49 and 52 between the same to the vertical conveyer 23 on the main frame.

To adjust the reel 75 in proximity and away from the sickle blade 39 there is provided a forked member 85 connected to the shaft 74 of said reel and having a real-wardly extending arm or rod 86, the rearmost end of which is pivotally connected as at 37 to a throw lever 88 to be actuated by the operator of the machine.

Rising from the main frame 10 and under the superposed frame is an upright 99 to which is pivotally connected a manually operable throw lever 91 having a drop curve as at 92 en aging a pin 93 projecting from the upright bar and said lever has connection with a depending bar 94 braced at the middle of the superposed frame on its under side and which throw lever is adapted to raise and lower the supplemental frame 36 which latter is held in its adjusted position by the locking pin 93 detachable from the said upright on the main frame Journaled in bearings 96 on the main frame is a bunch delivery or dropper means comprising a rotatable shaft 97 horizontally disposed in the main frame adjacent the conveyer 23 and having spaced hubs 98 with radially iprojecting arms 99 which support a bunch 0' material collected from the downwardly moving conveyer 23 and which material is delivered )eriodically in bunches to the ground. To old the bunch delivery lll means against movement until a predetermined amount of material has been cut thereby to form a bunch there is provided a trip lever 100 which is arranged in the path of the arms to engage the same as the delivery means rotate. The said trip arm 100 is pivoted to a boxing 101 mounted upon the main frame in which works a pivotal stem 102 connected to said trip arm and terminating in an enlarged head 103 which has its bearing against one end of a tension spring 104 the opposite end of the latter having its bearing against said boxing 101 and which spring serves to support and hold the trip arm 100 in a position to engage an arm 99 so as to hold the bunch delivery mechanism against rotation until a predetermined amount of severed material has been cut by the said arms to overcome the tension of the spring 104 to disengage the trip arm 100 from the arm of the bunch delivery mechanism whereby the latter will by gravitation gather the bunch of material to the ground.

To deflect the materialfrom the conveyer 23 so that the said material will be caught by the bunch delivery wheel there are provided spring fingers 105 secured to the vertical frame and extending downwardly at an clination beyond the conveyer 23 so that the severed material will be positively trans ferred to the bunch delivery means.

Adjacent the vertical conveyer 23 is a shield plate 107 depending from the supplemental frame 36 and telescoping between spaced guide plates 108 mounted upon the main frame and which shield plate serves to accumulate the severed material being carried downwardly by the conveyer 23 to be delivered to the bunch delivery means on the main frame of the machine.
